Slubber or fly-frame.



,Witwen srnras To all w omit 'may concern:

Be it known thi-.t l, RICHARD B. DALY, a citizen of tlie United States, and resident of Woonsocket, count-y o Providence, State. of Rhode Island, have invented an Improves ment in Shibbers or Fly-Frames, of which the folloi 'ing description, in connection with the accompanying drawing, is a specification, 'like' letters on the drawing representing like part-s.

This invention relates' more particularly to sluhbeis or flv-frames, and it ias for its object. the protuction'ri" novel and ellicient mechanism for positively driving the bobbinsha'its from the coiii}iouiid" on the main lshaft in such manner t iat en absolutely uniform speed of the bobina-shafts .vill he iiiaintained at all times throughout the traverse of the liobbiiirail.

As will hereinafter appear the construction of the mechanism forming the subject inatter of mv invention is simple, there is `no liability of its getting out of order, it can be readily applied, and is Wholly automatic in its ope-ration.

The various novel features of my invention will be fully described in the subjoined speciication and particularly pointed out in the following claims.

sLUBB' n on rLYlrRAME.

Patented Aug. 11, 190.8.

A diiviiify member, sho'ivn as a sprocket 10, is mounted on the main shaft A and connected with the hub I" of thc usual compound gears, not shown, said member 10 being connected by a s )rocket-chain or driving connection 11 with the sprocket -S of the transmitter, whereby rotation of the hitter is The drivingr connection 11 is maintained properly taut by longitudinal adjustment of the carrier 3, as will he obvious, the carrier having a vertical swinging movement upon the shaft A so that the trziiisiiiit-ter will have a bodily movement concentric with the driving member or s uoeket l0.

A driven mem er, shown as a sprocket 12 is fixedlv secured to the bobbin-shaft D, on a sprocket chain 1 3 connects said driven member and the sprocket 9 oi the transmitter, whereby rotation of the latter effects rotation of the bobbin-shafts C and D.

It will be seen from the foregoing that the transmitter is connected by the separate connections 11 and 13 with the driving member 10 and driven member 12, respectively, so.

effected.

The upper edge of the plate 14 is shaped to resent a cam 17 u on which the bearing', is slidably supporter the cam beingva circular are having the center of thc humain-shaft D as itscenter. The connection or chain 13 is maintained properly taut by adjustment oi the camfpla-te or support 14, es will be apparent.

As the bobbin-rail rises and falls the suport 14 will cause the transmitter te rise and rall in absolute unison therewith, the carrier 3 rocking on its fulcruin A and at the same time the transmitter will nave s back and forth movement upon and relatively to the.

cam 17.

As the cani is concentric ith the bobbin shaft; D and the driven member orsproeket 1'2 it will be manifest that the back and forth `.evenient of the transmitter n'iil not in any 50 means to eff ect bodily movement. thereof con# y 6. and as a consequence there is neither gain nor loss at any time dui'in the traverse of the bob `in-rzi-il, in the rotative movement of the driven member 12 derived from -the driving member through the intervening i connections. Accordingly the speed of the shaft-s Gand D will be 'absolutely uniform at all times throughout the traverse, with no possibility of back lash or lost motion, and resulting in an even wind to the yarn. At

. the same time the power is transmitted from the d riving member to the driven member 12 positively and directly, in an extremely simple manner, and with no tendency of the mechanism to get out of order.

The transmitter has a movement which is positively governed by the arm or carrier on which the transmitter is mounted and by the supporting cam, upon which the transmitter bearing has a sliding movement. A

In actual practice I am enabled, with the construction herein shown and described, to4

move the bobbin-rail `from one to the other end of its stroke. (the main shaft being .at rest) without the slightest angular movement of the bobbinshafts.

Having fully described my invention, what I claim es new and desire to secure by Letters Patent is 4 1. 4In a slubber or iiy-frame, in combination, a driving sprocket, a vertically movable bobbin shaft having an attached driven sprocket, a transmitter, connections between it and the said sprockets, to rotate the driven sprocket and bobbin-shaft from the driving sprocket, and means to cause the transmitter to move' concentric with both sprockets throughout the vertical movement of the bobbin-shaft.

2. In a slubber or ilydrame, in combination, a driving member, a driven member, a vertically movable bobbin shaft rotatable with said driven member, Aa. transmitter,

centric with both members during vertical movement of the bobbin-shaft, and separate, positive drivin connections between the transmitter an 'said driving and driven members.

3. In a slubber or {1y-frame, in combination, a driving member, a driven member, a

vertically movable bobbin shaft rotatable with'said driven -nieniber, a duplex connection bve-tween said members, a transmitter common to both parts of such connection, andmeans to cause said transmitter to move vertically in unison'with the bobbin-sliaft while maintaining constantfgdistances from the axes of rotation of the driving and drivenl niembeis.- 4. In a slubber or fly-frame, in'lioiniiination, a driving sprocket, a vertically movable bobbin shaft having an attached driven s rocket, a transmitter, a swi'n ing carrier t erefor fulcrumed co-arially witi the driving sprocket, a sprockct-chein 'connect-ing the latter and the transmitter, a second chain between the latter and the driven sprocket, whereby the latter is rotated positively by the driving sprocket, and means to verticaly support the free end of the carrier and cause the transmitter to move bodily concentric with the driven s rocket during.. vertical movement of the bo Vbin-shat`t.

5. In a slubber or il frame, a driving` sprocket, a longitudinal y-adiustable carrier;

fulcrumed co-axially therewit i, a `transmitter rotatably mounted on said carrier and coni-4 prising two connected s rockets, a chain connecting one of them an the driving sprocket,

a verticall movable bobbin-shaft, a driven sprocket ast'thereon, a chain connecting- `said sprocket with the second one cf the transmitter sprocket-s, and a vertically ad instable cam upon which the transmitter isi slidably andvertically supported, said cam being concentric with the driven sprocket.

6. In a sliibbeif` or iiy -frame, a driving s' rocket, a carrier fulcruined co-'axially' terewith, a transmitter rotatably mounted on the carrier and comprising two connected sprockets, a chain connecting one of them and the driving sprocket, means to maintain the chain taut, a vertically movablebobbinshaft having an attached driven s rocket, a chain connecting it and the secon, sprocket of the transmitter, and means to effect vertical movement of the transmitter in unison 'ies with the bobbin-shet and maintain the second chain taut, the transiiiitter .moving bodily concentric with the'bobbin-shaft.

7. In a. slubber or ly-nramc, a driving sprocket, a vertically swinging carrier fulcriuned co-axially therewith and having at its free end a lateral bearing, a shaft rotata- Ably mounted in the bearing and having an attached sprocket at each end, a chain connecting one of said sprockets and the driving sprocket, a vertically movable bobbin-shaft, an attached driven s rocket, a chain connecting 'it and the secon of the sprockets on the carrier, and a cani vertically movable in unis'on with the bobbin-sliaft and upon which the bearin` on the carrier rests and is slidabie, substantie ly as and for the purpose described.

In testimony whereof, have signed my' name to this specifica-tion, in the presence of two subscribing iwitnesses.
